Just wondering what some of you are getting for oil pressure? I bought my car and had good pressure then when I did the first oil change I switched to Mobil 1 synthetic and the pressure dropped to like 35 on start-up and then would get as low as 20 after driving for a while. Went back to regular oil and its back to 40-45 all the time.

 

I had a similar problem. When i first purchased my car the oil pressure was way low until i used mobile 1 and a k&n oil filter. Now at wot oil pressure gets well over 60. Cruising its around 45-50.

 

Mine was the opposite though. Good pressure with regular oil then dropped when i went to Mobil 1 syn.

 

I dont care for mobil it seem to be thin and burns faster than any other oils I've used, maby try some 10w 30 or somthing I recomend valvoline syn 10w 30 with a K/N oil filter I use it on all my cars now and after 3000 the oil is still cleen I've used it for several years, It may be a matter of preference but I think their are better quailty products out their that work better.

 

use 5w30 M1 stays a lilttle over 40 at idle..around 60 while crusing and at wot goes well above 60..i have good pressure

 

I use Amsoil 10W30 and filter. At cold idle I get above 60, warm right at about 37 to 40 and over 60 at WOT.
I have a 228/232 .571 .591 at 112 cam.
Stock 00 oil pump

 

Thats what im getting now with Castrol GTX but get tired of changing my oil every other month when it hits 3000 and want a syn oil. Has anyone tried Royal Purple?? Heard its good but its expensive

 

Castrol Syntec 10W-30. 163k miles. 60 psi upon start up. 35 when warm and idling.
